Calculate the BTUs for yourconfiguration at •40% to 55% relative humidity*•The 40U-P weighs 198 KG (435); a cabinet fully configured with EMC products can weigh approximately 1,182 kg (2600 pounds).Make sure your flooring can safely support your configuration. Calculate the minimum load-bearing requirements for your site using the product-specific weights for your system components at •0 to 2439 meters (0 to 8,000 feet) above sea level operating altitude*•LAN and telephone connections for remote service and system operation* Recommended operating parameters. Contents of the cabinet may be qualified outside these limits; refer to the product-specific documentation for system specifications.Air quality requirementsThe products are designed to be consistent with the requirements of the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) Environmental Standard Handbook and the most current revision of Thermal Guidelines for Data Processing Environments, Second Edition, ASHRAE 2009b.Cabinets are best suited for Class 1 datacom environments, which consist of tightly controlled environmental parameters, including temperature, dew point, relative humidity and air quality. These facilities house mission-critical equipment and are typically fault-tolerant, including the air conditioners.The data center should maintain a cleanliness level as identified in ISO 14664-1, class 8 for particulate dust and pollution control. The air entering the data center should be filtered with a MERV 11 filter or better. The air within the data center should be continuously filtered with a MERV 8 or better filtration system. In addition, efforts should be maintained to prevent conductive particles, such as zinc whiskers, from entering the facility.The allowable relative humidity level is 20 to 80% non condensing, however, the recommended operating environment range is 40 to 55%. For data centers with gaseous contamination, such as high sulfur content, lower temperatures and humidity are recommended to minimize the risk of hardware corrosion and degradation. In general, the humidity fluctuations within the data center should be minimized. It is also recommended that the data center be positively pressured and have air curtains on entry ways to prevent outside air contaminants and humidity from entering the facility.2For facilities below 40% relative humidity, it is recommended to use grounding straps when contacting the equipment to avoid the risk of Electrostatic discharge (ESD), which can harm electronic equipment.As part of an ongoing monitoring process for the corrosiveness of the environment, it is recommended to place copper and silver coupons (per ISA 71.04-1985, Section 6.1 Reactivity), in airstreams representative of those in the data center. The monthly reactivity rate of the coupons should be less than 300 Angstroms. When monitored reactivity rate is exceeded, the coupon should be analyzed for material species and a corrective mitigation process put in place.Storage time (unpowered) recommendation: do not exceed 6 consecutive months of unpowered storage.Fire suppressant disclaimerFire prevention equipment in the computer room should always be installed as an added safety measure. A fire suppression system is the responsibility of the customer. When selecting appropriate fire suppression equipment and agents for the data center, choose carefully. An insurance underwriter, local fire marshal, and local building inspector are all parties that you should consult during the selection a fire suppression system that provides the correct level of coverage and protection.Equipment is designed and manufactured to internal and external standards that require certain environments for reliable operation. We do not make compatibility claims of any kind nor do we provide recommendations on fire suppression systems. It is not recommended to position storage equipment directly in the path of high pressure gas discharge streams or loud fire sirens so as to minimize the forces and vibration adverse to system integrity.The previous information is provided on an “as is” basis and provides no representations, warranties, guarantees orShock and VibrationProducts have been tested to withstand the shock and random vibration levels. The levels apply to all three axes and should be measured with an accelerometer on the equipment enclosures within the cabinet and shall not exceed:Platform condition Response measurement levelNon operational shock10 G’s, 7 ms durationOperational shock 3 G’s, 11 ms durationNon operational random vibration0.40 Grms, 5–500 Hz, 30 minutesOperational random vibration0.21 Grms, 5–500 Hz, 10 minutesSystems that are mounted on an approved package have completed transportation testing to withstand the following shock and vibrations in the vertical direction only and shall not exceed:Packaged system condition Response measurement levelTransportation shock10 G’s, 12ms durationTransportation random vibration• 1.15 Grms• 1 hour Frequency range 1–200 Hz3Cabinet ClearanceThis cabinet ventilates from front to back; you must provide adequate clearance to service and cool the system. Depending on component-specific connections within the cabinet,15-foot extension power cords are required.Figure 1. Cabinet ClearanceThe illustrations in this guide are examples only. Depending on what your ordered, your cabinet may look somewhatCabinet stabilizingIf you intend to secure the optional stabilizer brackets to your site floor, prepare the location for the mounting bolts. (The additional brackets help to prevent the cabinet from tipping while you service cantilevered levels, or from rolling during minor seismic events.) The brackets provide three levels of protection for stabilizing the unit:•Anti-tip bracket - Use this bracket to provide an extra measure of anti-tip security. One or two kits may be used. For cabinets with components that slide, we recommend that you use two kits.All measurements are in inches.EMC2853•Anti-move bracket - Use this bracket to permanently fasten the unit to the floor.4Seismic restraint bracket - Use this bracket to provide the highest protection from moving or tipping.•All measurements are in inches.EMC2856Site floor load-bearing requirementsInstall the cabinet in raised or non-raised floor environments capable of supporting at least 1,180kg (2,600 lbs.) per cabinet. Your system may weigh less, but requires extra floor support margin to accommodate equipment upgrades and/or reconfiguration.In a raised floor environment:•24 x 24 inch or (60 x 60 cm) heavy-duty, concrete filled steel floor tiles are recommended.•Use only floor tiles and stringers rated to withstand:○concentrated loads of two casters or leveling feet, each weighing up to 1,000 lb (454 kg).○minimum static ultimate load of 3,000 lb (1,361 kg).○rolling loads of 1,000 (454) kg). On floor tiles that do not meet the 1,000 lb rolling load rating, use coverings such a plywood to protect floors during system roll.•Position adjacent cabinets with no more than two casters or leveling feet on a single floor tile.5•Cutouts in 24 x 24 in tiles must be no more that 8 inches (20.3 cm) wide by 6 inches (15.3 cm) deep, and centered on the tiles, 9inches (22.9 cm) from the front and rear and 8 inches (20.3 cm) from the sides. Since cutouts will weaken the tile, you can minimize deflection by adding pedestal mounts adjacent to the cutout; the number and placement of additional pedestal mounts relative to a cutout must be in accordance with the floor tile manufacture's recommendations.When positioning the cabinet, take care to avoid moving a caster into a floor tile cutout.Ensure that the combined weight of any other objects in the data center does not compromise the structural integrity of the raised floor and/or the subfloor (non-raised floor).We recommend that a certified data center design consultant inspect your site to ensure that the floor is capable of supporting thesystem and surrounding weight . Note that actual cabinet weight depends on your specific product configuration; you can calculate your total using the tools available at Casters and leveling feetThe cabinet bottom includes four caster wheels. The front wheels are fixed; the two rear casters swivel in a 1.75-inch diameter. Swivel position of the caster wheels will determine the load-bearing points on your site floor, but does not affect the cabinet footprint. Once youhave positioned, leveled, and stabilized the cabinet, the four leveling feet determine the final load-bearing points on your site floor.CL3627FrontRear viewRear viewNote: Some items in the views are removed for clarity.(see detail A)Dimension 3.620 to center of caster wheel from this surfaceDetail A(right front corner)1.750Caster swivel diameterDetail B Bottom view Leveling feetAll measurements are in inches.The customer is ultimately responsible for ensuring that the data center floor on which the system is to be configured is 6Power requirementsDepending on the cabinet configuration and input ac power source, single or three-phase, the cabinet requires two to 12 independent power sources. To determine your site requirements, use the published technical specifications and device rating labels. This will helpprovide the current draw of the devices in each rack. The total current draw for each rack can then be calculated. For Dell EMC products,visit the "Dell EMC Power Calculator" on the web at .Table 1.
